Ear PPT Summary
- The ear is crucial for both hearing and balance, with distinct roles performed by its various parts.
- The auricle consists of elastic cartilage and features such as the helix, lobule, and tragus, which aid in sound collection.
- The tympanic membrane, or eardrum, acts as a barrier between the external and middle ear and plays a key role in sound transmission.
- Blood supply to the auricle is primarily from the posterior auricular and superficial temporal arteries, with complex innervation from cranial nerves.
- External ear injuries can lead to serious conditions such as auricular hematomas, while inflammation of the external acoustic meatus can result in otitis externa.
